Copy Performance Test

A common everyday situation is simulated here. Three test folders are created:

  • ISO (folder with two large files)
  • Program (folder with many small files)
  • Game (folder with small and large files)

The three folders are copied using the Windows Copy command (the cache remains enabled). The practical test of February 16, 2023 shows the performance for simultaneous write and read operations. The lower the duration, the better the performance.

HD Tune Pro Endurance test

A long-term test was performed here to make full use of the memory capacity. You can see when a cache is full and the writing performance decreases. A test file of 4 GB was written to the medium.

HD Tune Pro Benchmark

HD Tune writes a 1 GB file to the 128 GB SSK USB flash drive. The transfer data of the read speed is displayed graphically. The minimum, maximum and average values are also determined. The determined access time and burst rate are also displayed.

ATTO Disk Benchmark

Here, a 256 MB file is written several times to the 128 GB SSK USB flash drive . The I/O block size varies (from 512 bytes to 64 megabytes). The larger the blocks, the faster they can be written and read.

SSD-Z Benchmark

Similar to HD Tune, a 500 MB file is written to the 128 GB SSK USB flash drive here. is written. The transfer data is displayed. The more constant the line, the better.
